DNA structure. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).The order of these bases is what determines DNA's instructions, or genetic code.ach nucleotide contains a phosphate group, a sugar group and a nitrogen base.

If a sequence of bases on one strand of DNA is CTGCTA, then the other DNA strand will be GACGAT. The Structure of DNA, RNA, and DNA's Arrangement in Cells DNA is Composed of Four Types of Nucleotides Since the 1920's, scientists have known that the DNA molecule is a very long polymer, or string of repeating units. The small units, or monomers that make up DNA are called nucleotides. Nucleotides Each nucleotide in DNA consists of three parts.
